5.3.3 Welding torch cooling system
Material damage due to unsuitable coolants!
Unsuitable coolant, coolants mixed with other types / liquids or use in an unsuitable tempera-
ture range will result in material damage and loss of the manufacturer's warranty!
• Operation without coolant is not permitted! Dry running will destroy the cooling components
such as the coolant pump, welding torch and hose packages.
• Only use the coolants described in these instructions for the specified ambient conditions
(temperature range) > see 6.1.1.1 chapter.
• Do not mix coolants of different types (including those described in these instructions).
• When changing the coolant, all liquid must be replaced and the cooling system flushed.
Dispose of the coolant in accordance with local regulations and the material safety data sheets.
